Overview
The Ubiquiti USL-Siren is an all-weather SuperLink siren designed to provide audible and visual security alerts within a UniFi Protect deployment. It delivers a 110 dB alarm and emergency LED lighting, with power provided by four CR123A batteries or a 12–24V DC source.
SuperLink Connectivity
The USL-Siren communicates using Ubiquiti's proprietary SuperLink wireless technology. A SuperLink Gateway is required for operation. The radio system provides a specified maximum range of up to 2 km (1.2 mi), subject to the installation environment and radio conditions.
Alarm and Emergency Lighting
The siren provides a 110 dB audible alarm together with an emergency LED light ring for visible notification. System and status indicators use multiple LED colors, while the light ring supports red, green, blue, and white illumination.
Power Options
The USL-Siren can operate from four CR123A batteries or a 12–24V DC power source. Maximum power consumption is 5W. The unit provides dedicated power and signal input terminals for wired power and signaling connections.
Installation and Environmental Protection
The siren supports wall mounting and ceiling installation using the included ceiling mounting plate. Its aluminum alloy and polycarbonate enclosure is rated IP56 for protection against dust and water exposure, making it suitable for indoor and appropriate outdoor installations.
